SPECFIGATION forming part of LettersPatent No. 396,810, dated January 29, 1889.

Application led "September 5, 1887. Serial No. 248,770. (No model.)

To @ZZ whom. it may concern.-

Be it known that we, SAMUEL B. COX and JOHN \V. ANDERSON, citizens of the VUnited States, residing at Lancaster, in the county ot Lancaster and State ot' Pennsylvania, have invented certain Improvements in Fittlr Iheels for Vehicles, ot' which the following is a specification.

Our invention relates to fifth-Wheels for carriages and wagons in which the king-bolt is set backot theaxle; and the objects of our improvements are, first, to pei-init a vehicle using our h tth-wheol to turn in a smaller space than that required with the fifth-wheels ordinarily attached, and, second, to prevent the accidental disconnection ot the parts in a more perfect manner than in the vehicles as new constructed. XVe attain these objects by the mechanism illustrated in the accompanying drawings, in whichm Y Figure l is a top or plan viewof our invention; Fig. 2, longitudinal vertical section through the line .r of Fig. l; Fig. 3, a front elevation ot' the ifth-Wheel. Fig. 4 shows a sectional View, on the line a, of our invention as applied to a straight perch 3 and Fig. 5 is a vertical section through the line y of Fig. l, showing the manner in which the iianged lug of the axleeplate engages the recess of the ii'fth-ivheel.

Similar letters indicate like parts throughout the several views.

In the drawings, A represents a iiftlrwheel plate resting upon the axle-plate B and having an arm, L, extending rearwardly from the forward portion thereof, by which it is connected With the perch D by the kingbolt O. The plate A and perch are further secured by a bolt located back ofthe king-bolt. A perchplate, F, is secured to the perch on the under side, and extends forward beyond the axle H and engages the fifth-Wheel and axle-plates by means et the clip f, formed integral with it.

lr is a flanged lug on the periphery of the axle-plate, which engages the groove g in the side of the iit'th-Wheel for assisting to keep the parts parallel While moving.

To prevent the disconnection of the parts, there are stays I, formed integral with the axle and joined together at the king-bolt by an eye, K. rlhis eye has a ilanged lug, k, on its back edge, which engages the circular recess 7' in the end ot' the 'rearwardly-extending arm L of the plate A.

The perch may be either curved or straight. In this specification the curved perch, Figs. l, 2, 3, and 5, is used to illustrate our prnciple. The application of the saine to a straight perch is illustrated in Fig. Li. Here the rearwardly-extending arm R, having a lip, r, of

the axle-plate B performs the functions al1A lotted the stays I in the other forni of coiistruction. I

I-Iaving thus described our invention, what We claim as new, and desire to secure by Leters Patent, is-

The combination, with the perch D, of the plate A, having the rearWardly-extending arm L, provided with a recess, j, the axleplate B, the perch-plate having the clip f, which engages the peripheries of the plates A and B, a connection between the axle and king-bolt, located beneath the arin L of the plate A and provided With a flanged lug Which engages the recess in the said arm L, and the kingbolt, all constructed and arranged substantially as described.
